Once you have this information, the first step in working out your ROI is
to establish how many contracts you could have
bought. We're going to be very conservative in this example and work
with a bank of $5,000 risking 5% (or $250) per trade.
With this trading profile, you can see from the calculation box on the left
how many contracts of each option you would have been able to
purchase (and that for some, they would have been too expensive for
you to trade).
